    摘要: A process for creating porous anode foil for use in an electrolytic capacitor of an implantable cardioverter defibrillator is provided. The process includes electrochemical drilling a plurality of etched metal foils in sequence one after the other in a bath containing electrochemical drilling (ECD) solution initially having a pH of less than 5. Alternatively, an etched foil sheet may be passed through the bath in a substantially continuous manner such that a portion of said etched foil sheet is in contact with the ECD solution is electrochemically drilled to generate pores. Electrochemical drilling is achieved when a current is passed to the foil or portion of the foil sheet in solution. ECD replenishment solution having a pH of less than about 5 is added from a feed reservoir to the bath at such a rate so as to maintain a pH in the ECD solution in the bath of less than about 5, and ECD solution in the bath is removed to a waste reservoir at the substantially the same rate as the addition of the ECD replenishment solution to the bath.

    摘要: The present invention provides a method for reforming a capacitor of an implantable medical device, such as an implantable cardioverter defibrillator, wherein the capacitor has a nominal voltage. The method of reforming the capacitor comprises charging the capacitor to a first voltage that is above the nominal voltage of the capacitor, partially discharging the capacitor through system leakage, charging the capacitor to a second voltage that is above the nominal voltage, and discharging the capacitor through system leakage until the charge on the capacitor dissipates. The present invention also provides an implantable medical device having a capacitor reforming circuit for reforming the capacitor. Capacitors reformed according to the present invention have reduced charge time deformation compared to capacitors conventionally reformed at the nominal voltage.

    摘要: A method of producing a highly etched electrode for a capacitor from a foil is disclosed. The method comprises first applying a composition to the foil to form a plurality of deposits on the foil surface. The method then includes heating the deposits to form micron-sized features and etching the foil. Preferably, the micron-sized features facilitate etching of the foil surface at the location of the micron-sized features. After etching, the foil is optionally further processed in a combination of optional steps such as widening, forming and finishing steps. The controlled application and heating of deposits on the foil surface allows for positional control of tunnel initiation during etching. Thus, the present invention relates to a method of controlling the etching of a foil, such that tunnel initiation density and the location of tunnel initiation is controlled. By controlling the position of tunnel initiation, foils are etched more uniformly and have optimum tunnel distributions, thus allows for the production of highly etched foils that maintain high strength and have high capacitance. The present invention further includes an electrolytic capacitor comprising etched aluminum anode foils, which have been prepared using the methods of the present invention.

    摘要: A micro-denier fiber of less than approximately 2.0 microns is coated in a valve metal to a metal thickness of approximately 0.2 to 2.0 microns. In one embodiment, a long filament of coated fiber is wound on a spool in such a way that the maximum arrangement of fiber density is achieved For example, the spool may have a cross section exhibiting a hexagonal close-packed arrangement of the fibers. In another embodiment, a plurality of fibers may be grown or formed into a particular arrangement prior to coating. Once coated and arranged, the fiber mass is compressed and constrained so that shapes can be cut out in various thicknesses, such as, for example, approximately 50 microns to 5000 microns. Each sheet is sintered to bind the metal and remove the fiber, leaving a porous anode that can be oxidized and formed in the usual manner for a capacitor.

    摘要: A method of producing an electrode for use in the manufacture of electrolytic capacitors for implantable cardioverter defibrillators comprises first coating the foil with a photoresist, second, applying a holographic image to the photoresist, third, removing a portion of the photoresist to expose a portion of the foil and create a pattern of photoresist on the foil and etching the foil. Alternatively, the method comprises applying an oxide or metal layer to the exposed foil surface, removing the pattern of photoresist to create a pattern of oxide or metal and etching the foil. The patterns of photoresist, oxide or metal all retard or prevent etching of the foil where the foil surface is covered. This results in a pattern of unetched foil with the remaining area being heavily etched. The resulting patterns stop crack propagation through the etched portions to yield foils with high gain and improved strength.

    摘要: A metal or metal alloy foil substrate, preferably an unetched and uncoated metal or metal alloy foil substrate, such as but not limited to titanium, palladium, lead, nickel, tin, platinum, silver, gold, zirconium, molybdenum, tantalum, palladium-silver alloy, platinum-rhodium alloy, platinum-ruthenium alloy, and/or platinum-iridium alloy, is used as the cathode in an electrolytic capacitor, preferably an aluminum electrolytic capacitor having a multiple anode flat, stacked capacitor configuration. Despite a 120 Hz bridge capacitance measurement lower than with etched aluminum, the use of an unetched and uncoated metal or metal alloy foil cathode according to the present invention will inhibit gas production and not cause the capacitor to swell. Furthermore, an electrolytic capacitor built with a 30 micron unetched and uncoated foil cathode according to the present invention can deliver a stored to discharge energy ratio sufficient for use in pulse discharge applications, such as an in an ICD.
